Title: Improvements in or relating to multiplex communication systems
Inventor: FLOWERS THOMAS HAROLD
IPC: H04J3/00
Filed: 1949-03-07
Abstract: 707,373. Thermionic distributers. POSTMASTER GENERAL. July 20, 1950 [March 7, 1949], No. 6163/49. Class 40 (3). [Also in Group XL(c)] The interlaced channel pulses in a multiplex system are produced by first multiplexing the channels in groups, in such a way that the outputs from some groups overlap in time those from other groups, the group outputs then being multiplexed to a single channel or a lower number of groups. Distribution of the channel pulses to their indvidual channels at a receiver is effected by an inverse process. The receiver of a 20-channel system, comprises four normally blocked valves a ... d, which are unblocked cyclically by negative pulses P6 . . . P9, applied to valves a1 ... d1 respectively. The incoming pulse train from the channel MC is applied to the grids of valves a1 . . . d1, so that channel pulses 1, 5, 9 &c. are applied to the control grids of valves A; 2, 6, 10 &c. to the grids of valves B; 3, 7, 11. &c. to the grids of valves C and 4, 8, 12 &c. to the grids of valves D. These sets of five valves are cyclically unblocked at their suppressor grids in columns of four by longer positive puises P1 ... P5, each of which lasts four channel periods, to pass individual channel pulses to the anode circuit output transformers, only one of which is shown. In the similar transmitting arrangement, Fig. 5 (not shown), valves A . . . D receive the channel input signals and valves a ... d feed the common output channel. The pulses necessary to operate a 100- channel system using 30 pulse sources are discussed, Fig. 7 (not shown). Specifications 694,092, [Group XXXIX], and 707,379, [Group XL(c)], are referred to.

Title: Method of and apparatus for the manufacture of corner mounts for photographs and stamps
IPC: B42F5/06
Filed: 1951-03-16
Abstract: 691,640. Picture &c. mounts. PAPIERFABRIK FLEISCHER GES. March 16, 1951. [March 18, 1950] No. 6363/51. Class 11. A method of producing pocket type corner mounts for photographs and stamps, comprises joining together two-webs of sheet material, e.g. paper, transparent cellulose foil, fabric, or the like, along one or more lines which correspond to the contour of the containers to be produced, and cutting out the containers along these lines, at least one of the webs comprising at least one surface of thermally-adhesive material whereby the webs are cemented together by the application of heat and pressure. As shown in Fig. 1 a web of suitable sheet material runs off a supply reel 3 and a second web 4 runs off a supply reel 6, the two webs passing together between two rollers 8 and 10. In one arrangement one or both of the rollers 8 and 10 may be heated and so profiled that the webs 1 and 4, are joined together along a zig-zag path 14, Fig. 2. The resulting double web 11 then passes between stamping tools 12, 13, where it is cut into individual mounting corners, or strips comprising a plurality of corners. In an alternative arrangement the corners are cut from the web simultaneously with the joining together of the two webs between the rollers 8 and 10, the rollers being provided with suitable cutting edges. In a further arrangement the rollers 8 and 10 are feed rollers and the webs are joined along the path 14 by means of heated stamping tools 12, 13, which may at the same time cut up the joined webs. The webs are thus continuously passed through rollers 8 and 10 but are intermittently joined by the stamping tools 12, 13 over an area which may include a plurality of mounting corners. The corners can be cut out along the line 15, or instead of being cut out completely may be scored or perforated. The two webs may be of unequal width. The lower part of the corner may be gummed for mounting photographs in an album, and can be wider than the top part.

Patent GB-581431-A (GB)
Title: Improvements in or relating to the production of chlorinated derivatives of ethyl alcohol
IPC: C07C45/30
Filed: 1945-03-19
Abstract: Chlorinated derivatives of ethyl alcohol, comprising chloral and its hydrate and alcoholate, are prepared by reacting chlorine and ethyl alcohol at an elevated temperature while exposing the reaction mixture to actinic light irradiation.  Ethyl alcohol of 70 per cent to 90 per cent concentration may suitably be used. Preferably, the reaction is carried out below 90 DEG  C.  The light irradiation may be provided by daylight, an electric light bulb, a fluorescent lamp, ultra-violet light, a carbon arc or a mercury arc.  Operated as a batch process, the reaction may be carried out by passing chlorine into ethyl alcohol contained in a closed vessel and irradiated by a suitable light source at a temperature not exceeding 30 DEG  C. until the specific gravity of the reaction mixture is 1.07, continuing then at 50 DEG  to 60 DEG  C. and completing the reaction at 80 DEG  to 90 DEG  C. to produce a product of specific gravity 1.50 to 1.53.  In a semi-continuous operation, the above batch process is carried to completion, then, say, 80 per cent of the charge is removed and immediately replaced with a quantity of alcohol equivalent to 80 per cent of that which has been removed; chlorination may now be initiated at a higher temperature 50 DEG  to 60 DEG  C. over about 3 to 5 hours and completed at 80 DEG  to 90 DEG  C. following which 80 per cent of the charge is again removed and the procedure repeated. Operated continuously, the process comprises utilising two reaction vessels so connected by an overflow pipe that the first vessel operates two-thirds filled only.  Ethyl alcohol is reacted in the first vessel with the batch procedure described above until about 80 per cent of the theoretical amount of chlorine has been absorbed. Then fresh alcohol and 80 per cent of the theoretical amount of chlorine required for its complete chlorination are fed in simultaneously.  This displaces some of the product into the second vessel and when this is about two-thirds filled, the additional 20 per cent of chlorine is fed into the second vessel to complete the chlorination.  The first vessel is operated at about 50 DEG  to 60 DEG  C. and the second at about 80 DEG  to 90 DEG  C.  The time cycle for all these processes is 18 to 24 hours.  Using alcohol of 70 to 80 per cent concentration, the major product is chloral hydrate and with anhydrous alcohol, the alcoholate is predominant.  The reaction product may be treated with sulphuric acid and crude chloral recovered by distillation therefrom.  To prevent spontaneous polymerization of the chloral during processing and storage it is desirable to introduce a small amount of hydroquinone or other antioxidant.  Examples 1 to 3 illustrate the batch, semi-continuous and continuous processes described above, using 95 per cent ethyl alcohol; example 4 illustrates a batch process using 82 per cent aqueous ethyl alcohol; in all cases illumination is by means of a tungsten filament light bulb.
